Authorities now say that a 15-year-old Champaign boy who died after what was first reported as potential bullying actually died of a previously undiagnosed medical condition.

Champaign police said Wednesday that an autopsy in St. Louis found that Luke Miller died of an unspecified condition. The autopsy found no evidence that he was attacked.

"The autopsy did not reveal the presence of any trauma or significant injury that would be consistent with being attacked or beaten, but that Miller’s death was tragic and medically related," a police news release stated.

The St. Louis Medical Examiner's Office did not return a call from WILL.

Miller died March 11 at Barnes-Jewish Hospital in St. Louis a day after what was initially reported as an attack at Centennial High School. Miller was a Centennial student and his family said he had been bullied.

Champaign County State’s Attorney Julia Rietz said last month that, while the investigation was still being conducted, no evidence of a crime had been found.
